The cause of the sudden death of an employee at BYD's Xi'an plant is being investigated by police, although there have been no criminal charges.
The employee, 36, was found dead in a rented home on November 5. The case quickly topped search trends on China's social media Sina Weibo on Wednesday. Local police said no criminal leads were being pursued.
The employee's family said they believe that his sudden death was related to high-intensity overtime work. The employee's work record shows that he worked 26 days in October and about 12 hours a day, coupled with frequent night shifts.
However, the exact cause of his death remains unclear without an autopsy being completed.
After consultation, BYD agreed to pay the employee's family a one-time sum of 200,000 yuan.
